I couldn't realize the role of vasa recta as I see its both parts cancel each other and adds nothing to the hypertonicity of the interstitium. Could you help me in that dr😑😑
Note to self (what I think, maybe wrong): why is NaCl absorbed in the vasa recta only to a certain point and then it is secreted again? Because as it is being absorbed, the interstitium gets hypotoner and the gradient direction switches. NaCl has to go back to the interstitium to make it hypertone again. This can happen because the flow is slow enough to make the interstitium hypotone for a little while and get the gradient to switch and then the blood is gone before it can reabsorb NaCl again (reswitch). 10:12
Vasa recta transfer nacl back to interstitium every time during this process , the quantity of nacl increases in interstitium,where this many molecules of nacl goes ??
@@quickquick472t if we throw it back, and we start another cycle the loop of henle will give another solites and go on, now the meddula will keep being hyper tonique more and more than 1200 only
Because at the lowest part of vasa recta the blood acquires very high osmolarity and becomes highly concentrated. And now when it comes out of the inner medulla into ascending limb of vasa recta then blood is having higher concentration than the surrounding interstitium. And so solutes (NaCl) are thrown out and water goes into the vasa recta, to decrease its osmolarity.
7:08 Mam isnt it the descending limb!!??? here im getting stuck...plz reply.....do,we determine ascending and descending on,basis of direction of filtrate??
In the descending limb of the vasa recta, when Nacl is absorbed shouldn't water follow it ??.. how is it the descending limb of the vasa recta takes in salt and give out water?
When blood flows down through descending limb of vasa recta there is increase in osmolarity(concentration) in surrounding so as water goes from high concentration to low concentration it goes out from vasa recta thereby increasing its osmolarity
Mam pls explain this qstn asked in NEET 2019 Use of an artificial Kidney during Hemodyalysis may result in a)Nitrogenous waste build up in the body b)Non elimination of excess K ions c)Reduced absorption of Ca2+ from GI tract d)Reduced RBC production Which of the following is most appropriate 1) c and d 2) a and d 3)a and b 4)b and c
1 Explaination: Artificial kidney cannot produce vitamin D so calcium will not be absorbed from GIT and it will also not be able to produce erythropoietin due to which RBC production will be decreased
mam thank you for your explanation it greatly helped me to understand the overall concept in my book there was no mention of osmolarity and interstitium they just said that the area around the descending limb is hypertonic so water flows out while the opposite at ascending limb with gibberish in between
Excellently explained!!!
I was remaining so doubtful in this topic for a long and now iam fully cleared with this topic after watching ur video.thank u mam thanksalot🎉
Thanks Alot Maam! Such a clear explanation! I am referring these videos in my Master's in Zoology for Physiology Paper and it is so helpful.👍🏻
All the best
in-depth and concise explanation and it helped a lot especially to explain to middle schoolers. Thank you for this video!
Well explined and clearly understood.Thanks a lot😊
Thankyou madam
Thankuuu madam... Can u Do more videos
Finally I got this explaination in English..👍.as most of this explaination are in Hindi!
Thanks madam. It's very useful for us to understand counter current multiplier mechanism.
Very nice ❤
That was so much helpful

Mam plz upload videos on plant haplontic diplontic cycle
that all no need! leave those topics waste topics
Well explained 👍👏
Gr8 help, thank U ma'am 😊😊
Nin ammun thanks ma'am
Nkn sike explanation
Once again thanks 🙏🙏🙏
Good and nice but I would. Like you to hilight on reproduction in plants
Thank you very much for the wonderful explanation!!!
thankyouuuuuuu
Thank u mam.concept clear 💓 😘 💖
Thank you
You are talented.
Good explanation madam,
Make a video on Muscle contraction theory that is sliding filament theory.
I already have, you can check it out!
Good job❤
Vasa recta transfer nacl back to interstitium every time during this process , the quantity of nacl increases in interstitium,where this many molecules of nacl goes ??
omg i finally understood, i cant thank you enough
Thank you very much. 🙏
Question: why does the vasa recta (ascending limb) need to give NaCl back to the interstitium?
To maintain the osmolarity in medullary interstitial fluid which is already created by counter current multipliers
@@quickquick472t if we throw it back, and we start another cycle the loop of henle will give another solites and go on, now the meddula will keep being hyper tonique more and more than 1200 only

And now when it comes out of the inner medulla into ascending limb of vasa recta then blood is having higher concentration than the surrounding interstitium. And so solutes (NaCl) are thrown out and water goes into the vasa recta, to decrease its osmolarity.
Thank you mam 🙏🙏❤️❤️
Thanks madam bt also talk about the counter current mechanism in thermoregulation
Thanks a lot
7:08 Mam isnt it the descending limb!!??? here im getting stuck...plz reply.....do,we determine ascending and descending on,basis of direction of filtrate??
Yes, descending and ascending is on the basis of direction of filtrate.

Ma'am I understood clearly
I was struggling to understand this concept
Thank you ma'am ❤
Can they be blocked? How and why
Explanation is good mam but it's too fast to understand the concept clearly.
Mam pls explain this qstn asked in NEET 2019
Use of an artificial Kidney during Hemodyalysis may result in
a)Nitrogenous waste build up in the body
b)Non elimination of excess K ions
c)Reduced absorption of Ca2+ from GI tract
d)Reduced RBC production
Which of the following is most appropriate
1) c and d
2) a and d
3)a and b
4)b and c

Thanks madam. It's very for us to understand counter current multiplier mechanism.
Not Bad.
I listened many lectures, watched many videos and I'm cleared at this lecture
Well done ❤❤
Thanku mam
Thanks much
Gr8 explanation ma'am, helped me to get it crystal clear.
loved it alot!❣️
